Is the following a bug?

    $ printf "aaa\nbbb\nccc\n\n" > 1
    $ printf "aaa\nbbb\n\nccc\n" > 2
    $ git diff --ignore-blank-lines 1 2

This shows a weird output, as if `ccc` was removed and then re-added.
Flipping the 1 & 2 names makes it show no difference at all.  I tried
a bunch of variants, including --minimal, and the four algorithms, and
all show the same results.  (Similar brokenness happens with an empty
line at the beginning on one side and after the first line on the
other.)

I'm really not sure that the following is a bug, because I see the
same behavior from `diff` (which is what made me try git-diff, hoping
that it would be more consistent).  (But I can't think of any rational
that would make it not a bug.)
